Read the passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

We seem to be entering a boom era for greenwashing - the tactic of covering routine pollution in eco-friendly language. [I] Picture running a high-emitting corporation: meaningful decarbonisation would demand painful negotiations, huge capital outlays, and a full redesign of the business model. Hiring an expert agency to splash "carbon- neutral" or "net-zero" across products is far easier, buying time while emissions remain untouched.

Consumers meet this sleight of hand everywhere. Airlines sell "carbon-neutral" flights, filling stations boast about "net-zero" fuel, and breakfast bacon is re-labelled as planet-safe. Advertising spin is old, yet today it is manipulated to conceal ongoing environmental damage. Social media influencers and glossy sustainability reports amplify these claims, broadcasting the narrative far beyond traditional marketing channels.

The term greenwashing emerged in the 1980s, an era of oil spills and growing climate science, but the practice has exploded only recently. [II] Intensifying public anxiety over global heating and ecosystem collapse has placed companies under sharp scrutiny; many boards therefore choose eye-catching PR over the tougher route of restructuring supply chains, energy sources, and product lines. Regulators on both sides of the Atlantic are struggling to police false eco-claims, yet enforcement still lags behind corporate ingenuity. Investors, eager to protect short-term returns, frequently applaud these surface-level initiatives, reinforcing the cycle. [III] No sector illustrates the issue better than oil and gas. Having realised that denying climate science now backfires, the industry has swapped denial for "green" paint. Press releases trumpet potential renewable ventures while drilling plans expand unabated.

Why does this matter? Greenwashing and climate denial share a core objective: to postpone the deep emission cuts claimed by scientists as urgent this decade. [IV] Whereas denial disputes the crisis, greenwashing misleads the public into believing problems are solved, thereby eroding consumer advocacy of genuine environmental actions and stalling regulatory reforms. In effect, it acts as a soothing lullaby, guiding society ever closer to ecological breakdown while fostering a false sense of progress. Exposing the facade-and insisting on verifiable, measurable carbon reductions-is essential if rhetoric is to give way to real action.

Where in the passage does the following sentence best fit?

Yet greenwashing is arguably more insidious.

Read the following passage about the Pathways from Today's Actions to Tomorrow's World and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

As we stand at the crossroads of environmental decision-making, the actions we take today will shape our world in 2050. Scientists warn that we're skating on thin ice with current consumption patterns and carbon emissions. Global temperatures could rise by 2-4 degrees Celsius unless significant changes occur within the next decade. Many countries have pledged to achieve carbon neutrality by 2050, but these promises require immediate implementation. Individual choices in transportation, energy usage, and consumption can collectively influence whether future generations inherit a sustainable planet or face severe climate consequences.

[I] Technological innovation represents our greatest hope for addressing environmental challenges by 2050. [II] Renewable energy sources like solar and wind are becoming increasingly affordable, potentially replacing fossil fuels entirely within thirty years. [III] Electric vehicles may dominate transportation networks, while vertical farming could transform food production in urban areas. [IV] However, these technological solutions must be developed and deployed equitably to avoid creating new disparities between wealthy and developing nations.

Social structures will undergo dramatic transformation by 2050 as demographic shifts reshape communities worldwide. Aging populations in developed countries will necessitate new approaches to healthcare, retirement, and social support systems. Meanwhile, climate migration may force millions to relocate from vulnerable coastal and drought-prone regions. Education systems must evolve to prepare our students for jobs that don't yet exist, emphasizing their adaptability and lifelong learning. Cities will need to become more resilient, incorporating green spaces and sustainable infrastructure to support growing populations.

Economic models must fundamentally change by 2050 to balance prosperity with environmental responsibility. The traditional focus on continuous growth may shift toward measuring success through wellbeing indicators rather than GDP alone. Circular economy principles will likely replace linear production models, with products designed for reuse and recycling. Resource-sharing platforms may become more prevalent, reducing individual consumption while maintaining living standards. Companies implementing genuinely sustainable practices will thrive, while those clinging to environmentally harmful methods may disappear entirely. The transition presents both challenges and opportunities for businesses willing to embrace innovation and sustainability.

Read the following passage about powering and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40. 

TikTok is a popular social media app where people can create and share short videos [I]. It started in China in 2016 as Douyin [II]. The app is known for its easy-to-use tools that let users add music, effects, and filters to their videos [III]. People of all ages enjoy making and watching TikTok videos, which can be funny, educational, or creative [IV].

One of the reasons TikTok is so popular is because of its algorithm, which shows users videos that match their interests. When you open the app, you see a personalized feed called the "For You" page. This page is different for everyone and updates with new videos all the time. Users can also follow their favorite creators to see more of their content.

TikTok has become a platform for trends and challenges. Many users participate in dance challenges, lip-syncing, and other viral activities. These trends can spread quickly, reaching millions of people in a short time. Because of this, TikTok has influenced music charts, fashion, and even language. Songs that go viral on TikTok often become hits on other platforms too.

The app is also a space for education and advocacy. Many creators use TikTok to share knowledge about various topics, such as science, history, cooking, and fitness. Others use the platform to raise awareness about social issues and promote positive change.

In addition to individual creators, many brands and businesses use TikTok for marketing. They create content to engage with their audience, often using popular trends and challenges to promote their products.

However, TikTok has faced some criticism and challenges. Concerns about privacy and data security have led to scrutiny from governments. Despite these issues, TikTok still remains one of the most downloaded apps in the world.
